The expansion of OpenRouter's models from 63 to 668 isn't caused by tracking; that's a classic failure mode in logic.
Just because someone's counting the models doesn't mean their spreadsheet is actually making more models appear.
The weakest link in that claim is confusing observation with causation—like saying my measurement of a wall built a room.
What matters is the actual mechanism for growth, which lies with the developers and providers releasing these new models, not with those tracking the numbers.
It's a quick way to snap to a wrong conclusion if you don't look past the data.
